MARS RECONNAISSANCE ORBITER HIRISE IMAGES
December 7, 2011

o Frosty Northern Dunes
  http://hirise.lpl.arizona.edu/ESP_024265_2535

  It is early spring in the Northern hemisphere of Mars, and
  these barchan dunes are covered with a layer of seasonal carbon
  dioxide ice.

o Crater Features

  At HiRISE resolution, we can better see the hollows and pits,
  along with the shapes of alcoves of gullies that are now filled up.

o Meanders and Tributaries in Ridge Form in the Zephyria Region
  http://hirise.lpl.arizona.edu/ESP_024484_1750

  This was once a river bed that meandered due to changes in
  topography.

o Interacting Fossae Segments East of Athabasca Valles
  http://hirise.lpl.arizona.edu/ESP_024576_1900

  Understanding the possible volume and flux of water in the ancient
  past may help in learning how the flood channel formed.
